Abstract

Introduction: Lung cancer is one of the leading causes of death worldwide and is closely related to smoking.

Objective: The objective of the study was to assess the Relative Risk of developing lung cancer in smokers in a health institution in Quevedo, Ecuador.

Methods: The study had a cohort design in which the Relative Risk was calculated in a population of 104 subjects from a health institution in Quevedo, Ecuador, using the Chi-square test.

Results: Chi-square tests showed a statistically significant relationship (p-value < 0.01) between smoking and the presence of lung cancer. Of the 104 participants, 55 had lung cancer, with 33 of them being smokers. On the other hand, of the 49 participants without lung cancer, 38 were non-smokers. This translates to a 60 % positive lung cancer diagnosis among smokers, in contrast to 22.4 % among non-smokers. Smokers were approximately 5.182 times more likely to develop lung cancer compared to non-smokers.

Conclusions: We conclude that smoking was significantly associated with an increased risk of developing lung cancer in this sample. These findings underscored the importance of smoking cessation as a key strategy for lung cancer prevention and supported the need for public health measures aimed at reducing smoking prevalence in this population.
